Cannabis hyperemesis syndrome

This code identifies a condition characterized by recurrent, severe nausea, vomiting, and abdominal pain in individuals with a history of chronic cannabis use. Symptoms typically improve with hot showers or baths and resolve with cannabis cessation.

Assign this code when documentation clearly indicates a diagnosis of cannabis hyperemesis syndrome, often presenting with cyclical vomiting and a history of regular cannabis consumption. Supporting documentation includes physician notes detailing the characteristic symptom pattern and the patient's cannabis use.

• Ensure documentation differentiates from other causes of cyclic vomiting or cannabinoid-induced nausea/vomiting (e.g., R11.10).
• Code also for cannabis dependence (F12.20-F12.99) or abuse (F12.10-F12.19) if present and documented.
• Do not use if the patient's symptoms are attributed to acute cannabis intoxication or withdrawal without the characteristic hyperemesis pattern.
